Plain English

Under Chicago, Ill., Mun. Code ch. 13-12 § 13-12-148, the Chicago Fire Commissioner is authorized to place first responder warning placards on hazardous vacant buildings—those that have been officially ordered closed, vacated, or shut down—to alert emergency personnel to serious structural or interior dangers. Once a placard is posted, entering the building without first notifying the fire commissioner is unlawful, as is covering, defacing, or removing the placard without written permission. The provision also allows the City to seek reimbursement from property owners for the costs of posting or removing such placards, and violations carry fines of $500 to $1,000 per day.

For Property Managers

Property owners subject to Chicago, Ill., Mun. Code ch. 13-12 § 13-12-148 should be aware that once a first responder warning placard is affixed to a building they own, entering that building—even for inspection or repair purposes—requires advance notification to the fire commissioner. Compliant operators also refrain from removing, covering, or defacing the placard without first obtaining written permission from the fire commissioner. Owners planning to demolish a placarded building must notify the fire commissioner in accordance with Section 13-124-070(b), and should anticipate that the City may seek reimbursement for placard-related costs as a collectible debt.
